How to use simple-keyboard in a Dashboard 2.0 template node?

I'm trying to figure out how I might be able to use simple-keyboard in a Dashboard 2.0 template node to create an on-screen popup keyboard whenever a Dashboard 2.0 text input field is selected.

I don't know or understand VueJS well enough yet to figure out how to adapt the "getting started" instructions for the Vue implementation of simple-keyboard.

Anyone have any suggestions for how to approach this?
